Abstract
An end effector for stapling and cutting tissue comprising a shaft portion extending along a longitudinal axis, a first jaw, and a second jaw is disclosed. One of the first jaw and the second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, wherein the second jaw is moveable relative to the first jaw between an open orientation and a closed orientation. The second jaw is configured to tilt laterally about the longitudinal axis between the open orientation and the closed orientation. The second jaw comprises an intermediate portion and a distal portion, wherein the distal portion is structured to clamp tissue against the first jaw before the intermediate portion when the second jaw moves from the open orientation toward the closed orientation.
